9 Binary Search
Problem Statement
Write Recursive Approach to Implement Binary Search Algorithm.
The problem is to implement the binary search algorithm using recursion. Given a sorted array and a target key, the algorithm should determine whether the key is present in the array or not.
Examples
| Sr # | Array | Input Key | Output |
|---|---|---|---|
| 1 | [1, 2, 3, 4, 5] | 4 | True |
| 2 | [2, 4, 6, 8, 10] | 5 | False |
| 3 | [3, 6, 9, 12, 15] | 15 | True |
Constraints:
- 1 <= nums.length <= 104
- -104 < nums[i], target < 104
- All the integers in nums are unique.
numsis sorted in ascending order.
Try it yourself
Try solving this question here:
java
public class Solution {
public static boolean binarySearch(int[] nums, int target) {
// Base Case: No rows to generate
return false;
}
}

🎨 Explain it visually
Build the mental picture, not memorization.
I just read a lesson on **9 Binary Search** (DSA) and want to truly understand it. Explain 9 Binary Search from first principles using ONE vivid real-world analogy and a visual mental model — draw it as ASCII art or a clear step-by-step diagram — with a concrete example using real numbers. Then ask me one question to check I got the mental picture, and wait for my reply. If you're unsure or a claim isn't standard, say so and reason from first principles instead of guessing.
🤔 Walk me through it (interactive)
Socratic — adapts to where you're stuck.
Teach me **9 Binary Search** interactively. Ask me ONE guiding question at a time, wait for my answer, and adapt to my confusion — build the idea with me step by step instead of explaining it all at once. If you're unsure or a claim isn't standard, say so and reason from first principles instead of guessing.
🧪 Quiz me & fix my gaps
Active recall exposes what you missed.
Quiz me on **9 Binary Search** with 5 questions, easy to tricky, ONE at a time. Tell me if each answer is right; at the end, explain clearly what I got wrong and why. If you're unsure or a claim isn't standard, say so and reason from first principles instead of guessing.
🧠 Make it stick
Intuition + hook + flashcards for long-term memory.
Help me remember **9 Binary Search** for the long term: give the one-sentence intuition, a memorable hook/mnemonic, a tiny worked example, and 3 active-recall flashcards (Q -> A). If you're unsure or a claim isn't standard, say so and reason from first principles instead of guessing.
